IT (ungrounded) systems
A drive equipped with no EMC filter or with EMC E210 is suitable for IT
(ungrounded systems). If the drive is equipped with EMC E202, disconnect
the filter before connecting the drive to an ungrounded system. For detailed
instructions on how to do this, please contact your local ABB representative.
WARNING!
If a drive with EMC E202 is installed on an IT system [an
ungrounded power system or a high-resistance-grounded (over 30 ohms) power
system], the system will be connected to earth potential through the EMC filter
capacitors of the drive. This may cause danger or damage the unit.
